The present invention provides a non-contact process for decorating dye-permeable fibres of a cosmetic applicator. The process comprises heating a dye-carrying surface of a carrier medium to a temperature sufficient to cause a dye plume to be released from said dye-carrying surface. The process further comprises placing said dye-permeable fibres of the cosmetic applicator at a distance from said dye-carrying surface in the path of the released dye plume, thereby allowing said dye to penetrate and decorate said dye-permeable fibres. The dimensions and the density of the dye plume can be optimised by controlled air flow. In an embodiment, the process comprises decorating all of the dye-permeable fibres simultaneously. Alternatively, the process comprises decorating only a portion of the fibres, the portion being either radial sections around a core to which the fibres are fitted, or longitudinal sections along the length of the core. In an embodiment, the distance between the free ends of the dye-permeable fibres and the dye-carrying surface is at least approximately 0.1 mm.
